HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 337,844, dated March 16, 1886.

Application filed November 11, 1884. Serial No. 147,666. (No model.)

T 0 all whom it may concern.-

Be it known that I, CHARLES J. LE ROY, of St. Louis, Missouri, have made a new and use fnl Improvement in Horseshoes, of which the following is a full, clear, and exact description.

The present invention relates to the calks of the shoe and the improved mode of attaching them to the body of the shoe, so that they can be readily removed and replaced, and especially so that the calks shall be securely as well as easily attached to the shoe-body.

The annexed drawings, making part of this specification, illustrate the mechanism employed in carrying out the improvement.

Figure 1 is a view in perspective of a horseshoe (inverted) having the improvement; Fig. 2, a similar View, the calks and their fastenings being removed; Fig. 3, a View in perspective of the outer fastening; Fig. 4, a View in perspective of one of the heel-calks; Fig. 5, a view in perspective of one of the keys; Fig. 6, a view in perspective of the toe-calk inverted, and Fig. 7 a similar view of a smooth toe-calk.

The same letters of reference denote the same parts.

A represents the body of the shoe. It is made of suitable material and preferably of malleable iron; but horseshoes composed entirely of malleable iron are liable to wear away too rapidly, and to obviate this difliculty the horseshoes are provided with steel calks B B C. These calks are similarly attached to the body A, and in the following manner: The calk is provided with a dovetail tenon, b. The tenon has a notch, 1), extending crosswise therein, the notch in depth extending into the body I) of the calk. The body, A, of the shoein shape conforms to the calks, having mortises a, in

which the tenons of the calks are received. 40

The dovetail recesses a are crossed by a groove, a. The calk is placed in its position by slipping it sidewise, so as to bring the tenon into engagement in the recess a. A key, D, is then inserted in the groove a, and as the keypasses through the notch b in its calk-tenon the calk is thereby fastened in the shoe-body A, and it cannot be removed therefrom unless the key is first removed from its place. The calk is therefore held by the key. The key, however, is liable to work loose. T0 confine it in its place, a band, E, of the form shown in Fig. 3, is passed around the projection a upon the shoe-body, in which the calk is held. The projection o as well as the key and calk, is grooved at (1 and the band, which is in the form, preferably, of a steel wire, is held in the recess formed by means of the grooves a a and the ends 6 c of the band are received in that part of the groove which is at the inner end of the projection a The wire E being elastic,it can be sprung around the projection, and when all the parts are together they assume the form shown in Fig. 1.

In the projection a at the toe of the shoebody A the slot at is used in place of the groove a in the projections a a at the heels of the shoe-body.

I claim The combination of the shoebody A, having the mortise a, the calk B, having the tenon b, the key D, and the band E, substantially as described.

CHARLES J. LE ROY.
